18 (Xinhua) — Israeli researchers say they have developed a reusable mask that connects a cell phone charging device to heat and kill the new crown virus. Professor Yair Ein-Eli, head of the technion research team, says the entire disinfection process takes only about 30 minutes, but masks are strictly prohibited when charging.
The new mask has a USB port that connects power sources such as a cell phone charging device and heats the inner carbon fiber to 70 degrees Celsius, enough to kill the virus.
Ein-Eli says the existing disposable masks are neither economical nor environmentally friendly, and “the masks must be reusable and (environmentally friendly), and that’s our solution.” “
Professor Allon Moses, an infectious disease specialist at Hadassah Medical Centre in Jerusalem, said 70 degrees Celsius and half an hour would certainly kill the new crown virus.
But he cautions that repeated heating can damage the paper or fiber used in the mask, thereby undermining its protective ness.
Ein-Eli said that during the test, the prototype mask was heated for 20 rounds at a time for half an hour, and durability was not affected.
